Fig. seven reveals an overlay of the two the sample UV spectra as well as the common UV spectra for peak B when detected at 310 nm. The UV spectra with the compounds detected within the cosmetics are advised to get precisely the same compounds because the conventional substance because the two UV spectra coincide. The use of PDA detectors can receive a UV spectrum, letting For additional reputable qualitative Investigation.
